The amp I have currently is great, but it lacks the low-end pump I need to play a low A or G string with. And for my major project of the year in my Woodwork class, I need something involving box construction, I figured I'd build an extension cab!

How difficult is this task?
Should I go 115 or 118? I have a 410 already, the cab will be an extension to give stronger lows.
What kind of wood should I be using?
How much is all the electronics + speaker + tweeter going to cost me?
How hard is it to wire the cab?

Thanks in advance.

Fatgoogle made a thread on this very topic a while back where a lot of questions on cab building were answered. I suggest you have a read through of it. Ill try and find it now.

Right first of use marine grade ply if you can, half an inch wide with bracing.

For the speaker i would go for a good 15" myself. A eminence kappa pro or the LF version. One of the best speakers you can get at the moment. Its about £100 so is pricey but will produce the low notes very well. With some speakon jacks, handles, covering etc will set you back around another £40-£70 depeddin on where you go and what you get. Let me reccommend bluearan.co.uk.

Now im new at this, so i say PM Phil Star after christmas and ask him about it, and he might be able to come up with some sizes and tunings for you.

Its not difficult atall to wire a cab, 5 mins but you just got to get them the right wa around.

thanks for the info. i was also wondering, when i'd be plugging this cab into the external speaker port on my amp, (its basically Edens 320w head built-in to their 410 cab) what's going to happen to the watts? are they going to be split in 2 among the cabs, 160 for each? and is splitting the watts like this going to reduce my volume?

No It won't be. It will be louder! It just reduces the load each cab has to take. 2 speakers is louder then 1.

I won't be able to stack them, as my combo 410, all the controls (plus input) are on the top, so i cant put this ext cab on top. and i cant put my 410 on top cuz it had wheels =\

what if i were to put them side by side?

You can unscrew the wheels with ease and attach them to your new cab - simple as a few srews.
And about side by side... It could affect the way your cab has to be built (that is, if you are making a bass reflex cab). I suggest just removing the wheels.

thats a good idea, thanks. is putting them side-by-side of any use though?

Side by side takes up more space. Also, Having a 1x15" underneath your 4x10", raises your 4x10" and makes it heard better, since it is elevated and directed at your ears.

Ok actually thinking about it, a 4x10 with good speakers will be better. Its easier for a 4x10 to go lower and produce at a better level thena 1x15 or 1x18. Youre 4x10 combo would most liely outperform the cab you would make. Mess around alot with your eq for a couple of hours.

Really? I already have a huge emphasis on my low mids. Next time at band practice, I'll try workin some EQ for it.
